T all whmiz it may) concern Be it known that I, HALSEY G. KINDER,

' residing at Chicago, in the county of Cook and State of Illinois, have invented certain of the instrument.

Among the principal objects sought to be accomplished by the invention are :to provide an automatic swell-shade action which 'may be'used interchangeablywith a manually controlled and operated actio and without any interference of either with the other; to provide a construction which will insure the preliminary closing of the swellshades, in case they happen to be open, upon the insertion of the music-roll inplaying position in the instrument; to provide a construction which will automatically effeet the opening of the shades gradually and to any extent desired and the subsequent closing of the shades in the same'manner at the proper points in the playing of the music record; to provide a construction auto- "music record; to provide a construction automatically effecting the disconnection of the power-operated parts of the swell-shade actuating mechanism at the conclusion of the automatic playing, leaving the instrument in normal condition for manual playing; to provide a construction insuring a noiseless actuation of the swell-shades; and,

provide a construction wherein the opening and closing movements of the swell-shades will be uniform in point of time, regardless of the tempo in which the piece is played, or, in other words, regardless of the speed of travel of the inusic sheet over the trackerrange.

Other objects and advantages of the invention will be apparent from' the following description, taken in connection with the accompanying drawings, in which Figure 1 is a diagrammatic view of the various instrumentalities and their connections employed in carrying out my invention, the illustration of the relative locations of the cooperating parts being conventional only. Fig. 2 is a front elevation of the swell-shades showing also the motor pneumatics and the interchangeable pedal-operated and motor-operated parts ofthe mechanlsm for actuating said swell-shades. Fig. 3 1s a detail in cross-section through the closed chamber containing the tracker-range and music-roll and receiving spools.

Referring to the drawings for a more detailed and complete explanation of the in- V vention and manner of its embodiment and operation, 5 and 6 designate two independently operable sets of swell-shades or shutters pivotally mounted in the usual manner in front of the main case containing the pipes. The individual. shades comprising the set 5 are pivotally connected at their-- upper ends for simultaneous movement by a bar 7, and the individual shades comprising the set 6 are connected in a-similar manner by a bar 8. Above both set-s of shades is slidably mounted an operating bar 9' for the shades 5, connected to the bar 7 by a link 10; and pivotally connected at one end to the bar 8 is a similar link 11. One end of the long operating bar 9 is pivotally connected to one arm of a bell-crank lever 12 that is pivoted at its elbow to a support 13. The other end of link ll is similarly connected to one arm of a bell-crank lever'14 pivotally mounted at its elbow on a support 15. Pivotally suspended from the other arm of elbow-lever 12 is a rod 16 passed through a guide 17 and similarly suspended from the other arm of elbow-lever 14 is a similar rod 18 passed through a guide 19. To the lower ends of rods 16 and 18 are pivoted depending links 20 and 21, respectively, connected to crank-arms 23 and 24 fast on rock-shafts 25 and 26, respectively. To other crank-arms 27 and 28 on the rockshafts 25 and 26 are connected rods 29 and 30 that are,' in turn operatively connected to the usual shade-operating pedals of the or an.

lhe parts thus far described are of known and ordinary construction in pipe organs.

31 and 32 designate a pair of main motor the operative faces of valves 36 and 37 are connected, respectively, to the latter, through stems 42 and 43, and serve to close the valves 36 and 37 when the motor pneumatics respectively controlled thereby are to be deflated. .Other bellows 44 and 45 similarly control the exhaust valves 38 and 39, respectively.

Pivotally suspended from the shutteroperating rods 16 and 18 are a pair of links 46 and 47, the lower ends of which lie directly above the motor pneumatic 31, and are provided with transverse holes or sockets 48 andv 49 in their lower portions, respectively.

Pivotally mounted at their lower ends in lugs 50 and 51 on the upper side of the motor pneumatic 31 are a pair of coupler links 52 and 53, the upper portions of which extend,somewhat above and behind the depending lower ends of the links 46 and '47, as clearly shown in Fig. 1, and are provided with laterally projectingpins or studs, such as 54 '(Fig. 1) adapted to cotiperate with the holes 48 and 49 to connect'up the links 46 and 52 and the companion links 47 and 53; it being evident that the links 52 and 46,

' when connected, serve to connect the motor pneumatics with the operating mechanism of the swell-shades 5, and the links 53 and 47, when so connected up, serve to connect the said motor pneumatics with the operating mechanism of the swelLshades 6.

Directly behind the upper ends of the links 52 and 53 are .a pair of pneumatics 55 and 56 having on the front leaf of their movable sides forwardly projecting studs 57 and 58, respectively, engaging the rear sides of the coupler links 52 and 53. f The pneumatics 55 and 56 are mounted on a valved wind-box 59 containing a wind chamber 60, ducts 61 leading therefrom to the pneumatics, an exhaust duct 62, and a valve stem 63 carrying valves 64 and 65 that control communication of the ducts 61 of the two pneumatics with the wind chamber and the exhaust duct 62, respectively. The valve stem is connected to a diaphragm 66 above a diaphragm chamber 67.

Beneath the pneumatics 55 and 56 are a pair of independentlycontrolled neumatics 68 and 69 provided on their movable leaveswith forwardly projecting lugs 70 and 71, respectively, that also engage the rear edges of the pivoted links '52 and 53. These pneumatics are mounted upon valved wind-boxes 72 each having a wind chamber 73, a duct 74 leading into the pneumatic, an exhaust duct 75, and a valve stem 76 carrying valves 77 and 78 controlling communication of the duct 74 with the exhaust and supply, respectively. The valve stem 76, beneath the valve 78 is secured to a diaphragm 79 above a diaphragm chamber 80, and the lower end of the valve stem rests upon, but is not connected to, another diaphragm 81 in an underlying diaphragm chamber 82.

83 designates a pivoted tablet, two such tablets being in this instance employed, which tablets are, in practice, usually lo cated above the manual or key-board. These tablets respectively control the inflation of the pneumatics 68 and 69, and, consequently, the connecting up of the separable shutter-operating connections previously described. Each tablet is connected at its lower end to a push-rod 84 which, in

turn, acts against a valve stem 85 in a "windbox 86. This latter has a vent-port 87 normally closed by a valve 88 on the valve stem 85. The inner end of the valve stem slides througha fixed guide 89; and the wind-box also has a duct '90 normally in free communication, with the wind chamber, to which duct is connected a pipe 91 that leads to the diaphragm chamber 82 in the bottom of the wind-box 7 2.'

92 designates the usual closed box containing the tracker-range 93, music-roll spool 94, perforated music sheet 95, and receiving or winding-up spool 96, said box having the usual sliding glass panel 97 at its front by which it may be opened for the introduction and removal ofthe music-roll.

These parts are all as usual, except that the tracker-range is provided with a pair of auxiliary ducts 98 and 99 preferably located at the extreme ends thereof, and an intermediate auxiliary duct 100 preferably located at the center. The stem 101 of the slidable chuck which supports one lend of the music roll spool 94 engages a springpressed valve 102 that controls a vent duct 103 formed in a block 104 secured to a side wall of the box 92, said valve 102 being normally urged to closing position by a spring 105.

106, 107, 108 and 109 designate as entireties a group of valved primary wind-boxes that are controlled from the music sheet and tracker-range'and the music-roll spool, and, in turn, effect the control of the actuating devices of the supply and exhaust valves of the main motor neumatics 31 and 32, in the manner and by, the means hereinafter described. The wind-box 106 contains a wind chamber 110, a lateral duct 111, a-vent duct 112 to the atmosphere, a diaphragm chamber 113, a diaphragm 114, above said diaphragm chamber, and a valve 115 resting on said diaphragm and controlling the communication of the lateral duct 111 with the wind chamber 110 and the vent duct 112. The diaphragm chamber 113 also has ableed vent 113. Similarly the wind-box 107 contains a wind chamber 116, a lateral duct 117, a vent duct 118 to'the atmosphere, a diaphragm chamber 119, a diaphragm 120 above said diaphragm chamber, and a valvedesignating the wind chamber, 124 the lateral duct, 125 the vent duct, 126 the diaphragm chamber, 127 the-diaphragm, 128 the valve, and 126 the bleed vent. -The wind-box 109 is an exact duplicate of the box 107 129 designating the wind chamber, 130 the lateral duct, 131 the vent duct, 132 the diaphragm chamber, 133 the diaphragm, 134 the'valve, and 135 the constant pressure supply connection.

A-p'pe 136 connects the duct 103 of the block 104 with the diaphragm chamber 132 of the primary wind-box 109 which is controlled by the music-roll spool. A pipe 137 connects the auxiliary duct 98 of the trackerrange with the diaphragm chamber 1260f the primary wind-box 108, through which the opening movement of the swell-shades 1s controlled. A pipe 138 connects the auxiliary duct 99 of the tracker-range with the diaphragm chamber 113 of the primary wind-box 106, through which the closing movement of the swell-shades is controlled, and a pipe 139 connects the central'auxiliary duct 100 with the diaphragm chamber 119 of the primary'wind-box 107, through which the swell-shades are brought to closed position and the power connections of the swellshades uncoupled as soon as the music-roll sheet passes off the tracker-range at the conclusion of the playing of the musical record. A pipe 140 connects the lateral duct 130 of the primary wind-box 109 with the diaphragm chamber 67 of the valve box 59.

From the foregoing it will be seen that the insertion of the music roll spool 94, by venting the duct 103 and pipe 136, allows pressure from the wind chamber 129 to pass through the lateral duct 130 and pipe 140 into the diaphragm chamber 67, raising the valves 64 and 65, and placing the Wind chamher '60 in communication with the pneu.

matics and 56 through the ducts 61, at the same time cutting ofl the vent duct 62.

vThis expands the'pneumatics 55 and 56 and throws the links 52 and 53 forwardly into coupling position relatively to the co6perating links 46 and 47. Simultaneously with this actuation of the pneumatics 55 and 56 to effect the coupling of the links of the shutter-operating connections, pressure is admitted to'the motor pneumatic 31, and the motor pneumatic 32 is placed in condition for exhaust through the following described mechanism.

Connected to and communicating with the pipe 140 isa pipe 1.41 that leads to the diaphragm chamber 142 of a controller 143, this latter containing a valve stem 144 having two valves 145 and 146, a vent duct 147 to the atmosphere, a lateral duct 148 between thevalves, and another lateral duct 149 between the lateral duct 148 and the diaphragm 150.to which the valve stem is connected.

From the lateral duct 148 leads a pipe 151 connecting with the valve-actuating bellows 40 of the motor pneumatic 31, said pipe 151 having a branch 152 leading to the exhaustvalve operating bellows 45 of the motor pneumatic From this it will be seen that the pressure in pipe 140 will also act through pipe 141 to raise the diaphragm 150 and the valves 146 and 145, thus venting pipes 151 and 152 to the atmosphere through ports 148 and 147, allowing the valve 36 to 'open to I admit pressureto the motor pneumatic 31, and opening exhaust valve 39 to permit the deflation of the motor pneumatic 32. Simultaneously with this operation, the supply valve 37 of the motor pneumatic 32 is closed and the exhaust valve 38 of the motor pneumatic 31 is closed'by the following mechanism: 153 designates a controller similar to the controller 143, having a diaphragm chamber 154, a valve stem 155 carrying two valves 156 and 157, a vent-duct 158 to the atmosphere, a lateral duct 159 between the valves, and .another'latera-l duct 160 between the lateral duct 159 and the diaphragm 161 to which the valve stem is connected; A pipe 162 connected to and communicating with thepipe 140 leads into the diaphragm chamber 154. A ipe 163 connectedto the lateral duct 159 othe controller leads into a diaphragm chamber 164 of a third controller 165 that is similar to the controllers 143 and 153; in the said cont-roller 165, 166 designating the valve stem, 167 and 168 the two valves thereon, 169 the vent duct to'the atmosphere, 170 the lateral duct between the valves, 171 'the lateral. duct below the duct 170, and 172 the diaphragm towhich the venting pipe 163 to the atmosphere through ducts 159 and 158, and so ventin diaphragm chamber 164 and permitting va ves 167 and 168 to occupy their lowered position. This places pipes 173 and 174 under" pressure through ducts 170 and 171 of the controller 165 and a pipe 175 that leads from a regulator 176 herelnafter described, said regulator containingoa wind chamber with which the pipe 175 is normally in communication.

It will be seen from the foregoing that the opening of the valve 102 and the venting of the duct 103 and pipe 136 by the outward sliding movement of the music-roll chuck-spindle 101, due to the insertion of the music roll spool, acts to simultaneously throw the links 52 and'53 into coupling position with relation to the links 46 and 47 admit motive fluid to the motor pneumatic 31, closing the exhaust valve of the latter,

and place the motor pneumatic 32 intoa condition to exhaust by closing its supply valve 37 and opening its exhaust valve 39. If it happens that one or both sets of swellshades are wholly or partially open, the links 52 and 53 will move upwardly until the pins 54 come opposite the sockets 48 and 49, whereupon the two sets of links will automatically couple. As soon as the music roll spool is returned to normal playing position by the engagement of the opposite end of the spool with its chuck and the release of the spool'from the hand of the operator, the Kent duct 103 is closed, and all of the described operations are automatically reversed, the pneumatics 55 and 56 being deflated, n'iot'or pneumatic 31 being also deflated, and motor pneumatic 32 being inflated, resulting in the bringing of the swellshades to. fully closed position by the simple operation of inserting the music-roll spool in its supporting chucks and before the music record sheet is engaged with the receiving spool and the tracker-range. As soon as the swell-shades have been thus brought to a fully closedposition, the links 52 and 53 are thrown back from the links 46 and 4"Lby springs 177 that normally tend to retract them. Of course, if, at the time of inserting the music roll spool, the swellshades happen to be in closed position, the

shutters will simply be given an idle preliminary opening and closing movement. While the coupler links 52 and 53 are under load, the friction of the pins or studs 54 in the sockets 48 and 49 is suflicient to maintain said parts in coupled relation against the action of springs 177. However, to prevent accidental uncoupling, which might oc-. cur under an up-and-down movement at the point where the direction of movement is reversed, I provide a simpleautomatic latch mechanism comprising the following parts: 232 designates a gravity latch pivoted at 233- to the lower end of each of the shutterwhen the latter is in its lowermost position and beneath the overhanging end of the.

latch is a fixed stop 238 that effects the au-' tomatic disconnection of the latch fromthe pin 236 as soon as the links46 and 47 reach their lowermost position. From this it will be seen that, as soon as the stud 54 enters the socket 48, the pin 236 will engage the latch 232, and the two links will be held in connected position until the latch 232 is automatically disengaged from pin 236 by the fixed stop 238 at the conclusion of the swellshade closing movement of the operating parts.

Referring now to the music-sheet and tracker-range controlled means for automatically opening and closing the swellshades during the playing of a record, 178 and 179 designate two groups of longitudinally alined slots or like openings formed in the marginal portions of the music record sheet opposite points in the music record at which the swell-shades are to be: opened and closed, respectively. The openings 178 cooperate with the tracker-range duct 98, and the openings 179 similarly coiiperate with the tracker-range duct 99. I The trackerrange box, as is well understoodf is, when closed, normally 'under a wind pressure of several ounces; and when the first opening 17 8 registers with the tracker-range duct 98, the pressure passes through pipe 137 to diaphragm chamber 126 of the shade opening primary 108, closes the valve 128, and places under exhaust through lateral duct 124'and vent duct 125 a pipe 180 that leads into the latter containing a valve stem 183 carrying valves 184 and 185, a vent passage 186 tothe atmosphere, a lateral duct 187 between the valves, a wind chamber 188, and a diaphragm 189 to which the valve stem is conncted. The exhausting of pipe 180 allows pressure from the'wind chamber 188 to pass through lateral duct 187 and a pipe 190 to a pneumatic 191 that cotiperates with a regulator 192 to control the admission and exhaust of'pressure to and from a pipe 193 leading from said regulator to the lateral duct 149 of the controller 143'. The regulator 192 contains a valve stem 194 and a lateral duct 195 to which the pipe 193 is, connected. A valve 196 on the valve stem normally closes the duct 195 to the atmosphere, and another valve 197 on the same valve stern controls communication of duct 195 with a' wind chamber 198, said valve being normally open. l The two valves are normally maintained in the relative positions shown by a spring199 that urges downwardly a trip lever 200 that is pivoted on a bracket 201 carried by the regulator box and isconnected to the upper end of the valve stem 194. On the movable side of the pneumatic 191 is a post 202, pivoted on which is a trip 203, one end of which is ada ted to engage and raise the free end of t e tri lever 200 when the pneumatic is expande while its opposite .end normally engages a stop 204 also carried by the movable side of the pneumatic. The inflation of the pneumatic 191, therefore, results in the raising of the trip lever 200 and the valves 196 and- 197, the trip 203 automatically returning to normal posltion when the pneumatic 191 is deflated, since its operating end or point is free to slide downwardly past the free end of/the trip lever 200;'the pneumatic 191 being normally urged to deflated osition by a spring 205. The described shi ting of the valves 196 and 197'through the pneumatic 19L cuts ofi the wind chamber 198 from the lateral duct 195, and exhausts pipe 193 to the atmosphere past the open valve 196. This likewise places under exhaust, through ports 149 and 148 of the controller 143, the pipes 151 and 152, whereby the-exhaust valve 39 of the motor. pneumatic 32 is allowed to open and the supply valve 36 of motor pneumatic 31 is alsov allowed to open. At this time the exhaust valve 38 of motor pneumatic 31 is held closed and the supply valve'37 of motor pneumatic 32 is also held closed by pressure from the-wind chamber of the regulator 17 6,

acting through pipe 175, ducts 171 and 170 of controller 165, (valve 168 being at this time open and valve 167 closed), and pipes 173 and 174. As the several openings 178 pass in rapid succession over the duct 98, the motor pneumatic 31 is expanded by a series of successiveuniform pulsations, the extent of expansion, and consequently the extent to which the swell-shades are opened, depending upon the number of perforations 178 in each group in the music sheet. In

practice I have-found that ten perforations I in each group give satisfactory results 'to effect a complete opening of the swellsh'ades, but, of course, this is optional. de-

pending mainly upon the sensitiveness of the Y apparatus. It should here be stated that,

' prior to or during the playing of the record,

the operator actuates either-or both of the tablets 83, by whicheither or -bothof the links 52 and 53 are coupledto the coiiperating links 46 and 47 of the shade-actuating mechanism through the pneumatics 68 and 69; This is done by venting the pipe 91 through the vent port 87, by pushing inwardly the valve stem This vents the diaphragm chamber 82 of the pneumatic wind-box 72, and allowspressure from the wind. chamber 73 to pass through duct 74 into the pneumatic, it being understood that, at'thi's time, the diaphragm chamber is under exhaust through a pipe 206 communicating at one end with the diaphragm chamber 80 and-at its other end with the lateral duct 117 of the stop primary 107. Said lateral duct 117 is in communicatiomat this: time, with vent duct 118 by reason of the closing of valve 121; said valve being closed at this time by the constant pressure admitted to the diaphragm, chamber 119 by the pressure supply 122, it being noted that the pipe 139 is closed at the auxiliary duct 100 by the music record sheet overlying said duct; it being further noted that, from the time the music record sheet is attached to the receiving roll until the playing of the music is completed and the music rol l unwound, the duct 100 is at all times closed by the music sheet, and consequently the wind chamber 116 of the stop primary 107 is cut oil by the valve 121. As soon as the first aperture 179 of the swell-shade closing group passes over the auxiliary port 99 of the tracker range, pressure from the trackerrange box acts through pipe 138 and diaphragm chamber 113 to close the valve 115,

and vent, through ducts 111 and 112, a pipe 207 that leads into the diaphragm chamber 208 of a relay 209 similar structually and functionally to the relay 182, said relay containing a valve stem 210 carrying valves 211 and 212, a vent duct 213, a lateral duct 214, a wind chamber 215, and a diaphragm 216 to which the lower end of valve stem 210 is connected. From the lateral duct 214 extends a pipe 217 that leads to a pneumatic 218 similar to the pneumatic 191 and cooperating in the same way with the regulater 176. In the regulator 176 the valve stem is designatednby 219, the lateral duct (with which pipe '175 communicates) by "220, the upper and lower valves by 221 and 222, respectively, the wind chamber by 223, the trip lever by 224, its supporting bracket by 225, and its returning spring by 226. The pivoted trip of the pneumatic 218 is shown at 227 its supporting post at 228, its stop at 229 and its returning spring at 230. The described exhaust of pipe 207 and diaphragm controller 143, and pipes 151 and 152, to

close the supply valve 36 of motor pneumatic -31 and also close exhaust valve 390i motorpneumatic 32.. This, manifestly, reverses.

swell-shades by a series of stepped movements during the travel of the series of openings 1,79 overthe auxiliary duct 99 of the tracker-range. a

The functions of the central duct 100 of the tracker-range, so far. as its relation to the present invention is concerned are to bring the swell-shades to closed position and also to effect the automatic uncoupling of the swell-shade actuating links 52 and .53 from their cooperating links 46 and 47 at the conclusion of the playing of the record, so as to always leave the instrument in proper condition for manual playing without requiring any preliminary adjustments or manual disconnecting of the automatic operating devices. So long .as the duct 100 is closed by the music-record sheet during the travel of the latter over the trackerrange, the valve 121 is held closed, and the pipe 206 and diaphragm chamber 80 are exhausted, so that the pneumatic 68 is ex panded and maintains the link 52 in operative engagement with the link 46. As soon, however, as the duct 100 is exposed by the passing ofi of the music sheet, and the tracker-range box is opened, releasing the pressure in the latter, the diaphragm cham-* her. 119 is vented, the valve 121 opens, and pressure from the wind chamber 116 passes 7 through duct 117 and pipe 206 to diaphragm chamber 80, closing valve 78 and opening valve 77, thereby venting pneumatic 68 and permitting the links 52 and 46 when fully lowered to be uncoupled by the spring 177 regardless of the manual re-setting to normal position of the tablet or tablets 83. The

duct 100 also effects a final closing movement of the swell-shades at the. conclusion of the playing of the music record, independently of the duct 99 and swell-shade closing apertures 179 of the record sheet, in the following way. A pipe 231 connected to and communicating with the pipe 206 leads into the lateral port 160 of the controller 153 above the diaphragm 161. When the duct 100 is opened by the passage of the tail-end of the record sheet off the trackerrange, the diaphragm chamber 119 is vented through pipe 139 and duct 100, and pressure from the wind chamber 116 flows through pipes 206 and 231 throughcontroller 153 and pipe 163, into diaphragm chamber 164 of controller 165, closing valve 168 and opening valve 167, thus venting pipes 173 and 174 and the valve-actuating bellows 41 and 44. At the same time "pressure'from wind chamber 198 of the regulator 192, acting through pipe 193, regulator 1.43, and pipes 151' and 152 closes valves 36. and 39, thus 7 pipe 231 is vented, so that pressure acting through pipe 162 is unopposed in the shift- -mg of valves 156 and 157 to vent the 163, and diaphragm eha-mber 164, as d sscribed in connection with the operation of the swell-shade closing mechanism controlled by-theinsertion of-the music-roll spool. a

I may here note ping devices 218 and 191 and the controllers that the use of the regulators 176 and 192 with their valve-trips 209 and 182 thereof is optional; the purpose of these devices being to secure opening and closmg movements of the swell-shades that shall bear a fixed relation in point of duration to the extent of travel of the music record sheet over the tracker-range during' such openin and closing movements, independently of the tempo in which the piece is played, and independently of the length of the sheet openings controlling said opening and closing movements. For instance, assume that a given piece is played twice at first very slowly, and subsequently in quick'time; ,and that the regulating devices are not em- :ployed'. At ,the first (slow) playing, the

tracker-ducts 98 and 99 would be flushed for a greater. length of time by each of the sheet openings 17 8 and 17 9, and this would result in a longer pulsation, and a greater, extent of movement of the motor pneumatics 31 and 32 at each pulsation, and consequently the shades might befullyopened or closed by the time the record sheet had traveled over the tracker-range to the extent of but onehalf the shade openings 178 or 17 9. At the subsequent (fast) playing, the tracker-ducts 98 and 99 would be flushed for a less length of time (due to the greater speed of the record sheet), and this would result in a shorter pulsation, and a less extent of movement of the' motor neumatics 31 and 32 at each pulsation, and consequently the shades would not be fully opened or closed until the record sheet had traveled over the trackerrange to the extent of all the sheet openings 178 or 179. Now, when the regulating devices are employed, the action of the regulator neumatics 191, 218, trips 203, 227, and regulator valves 19.6, 197, and 221, 222, is intantaneous and uniform in' point of duration, regardless of differences in the duration or extent of flushing of the trackerducts 98 and 99 due to slow orfast playing, or variations in the length of the sheet open- 35 of the air currents and the changes in the ings, '178, 179; and consequently the flushings of the trackerducts 98 and 99 produce pulsato movements of the motor pneumaticst at are always uniform or of equal extent and duration, regardless of the speed of travel of the music record sheet. In this way the said regulating devices insure a fixed relation between the duration of the opening and closing movements of the swellshades and the extent of travel of the record sheet over the tracker-range during such opening and closing movements, which is whollyinde ndent of the speed of travel of the recor sheet, and of variations in the lengths of the swell-shade controlling openings in the record sheet. This speed-regulating mechanism, however, as stated, may be omitted,and the described automatic operation of the swell-shades secured by simply connecting the pipe 180 directly to the pipe 193, cutting out the relay 182 and regulator 192 and its tripping mechanism, and by directly connecting the pipe 207 to the pipe 175, cutting out the relay 209, and the regulator 17 6 and its tripping device.

As it is impracticable to illustrate all of the relative positions which the numerous cooperating parts and devices assume before,

during, and subsequent to the playing of a musical record, I have illustrated in Fig. 1 simply the normal idle positions of the parts such as they would have when the apparatus is atrest' and the tracker-range box is not under pressure; and hence I have described in considerable detail the courses conditions and relative positions of the various parts that occur from the introduction of the music roll spool -to the completion of the rendition of the-music record.

From the foregoing it will be apparent that an organ embodying my improvements is always in condition for either manual or automatic playing regardless of the condition, as to the position of the swell-shades, in which it may have been left by previous playing, either manual or automatic, and without requiring any special manipulation or adjustment of parts to convert the-instrument from a condition of readiness for one style of playing to a condition of readiness for the other style of playing. The features of my invention, therefore, which relate to the automatic actuation of the swell-shade operating mechanism in a direction to close the shades upon the insertion of the music roll spool and to the automatic closing of the shades and uncoupling of the power actuated mechanism at the conclusion of the playing of the piece form adjuncts of considerable value to the main feature relating to the automatic actuation of the swellshades controlled by auxiliary apertures in the music record sheet and auxiliary ducts in the tracker-range.

It will bemanifest to those skilled in the art that, in detail structure and relative arrangement of the various cooperating parts described and shown, variations and modifications may, to a considerable extent, be .made without involving any departure from the principles involved or sacrificing any of; the benefits and advantages secured. Hence,

the invention is not limited to the particular embodiment'thereof illustrated and destlzr bed, except to the extent indicated in the c alms. I
